Title: Flash memory device
Inventor: KIM DAE HYUN
IPC: G11C16/34
Filed: 1996-08-09
Abstract: A flash memory device comprises a detection circuit 1 for confirmation of pass or fail at the time of confirmation of erase of a sector, a sector address counter 2 for selecting the sector, a sector address generator 3 having inputs connected to the output signals of the detection circuit 1 and sector address counter 2, a sector address decoder 4 having an input connected to the output signal of the sector address generator 3, and a multiplexer 5 connected to the output of the sector address decoder 4. The flash memory prevents over erase and stress of a cell by preventing re-erase of a sector, which was confirmed as a pass, at the time of re-erase operation due to the occurrence of a fail sector by storing the address of the sector, which was confirmed as a pass, at the time of the erase operation of a multi sector, so as to improve reliability of the product and the life of the cell. Circuits for the detection circuit 1, address counter 2, sector address generator 3, sector address decoder 4 and multiplexer 5 are described (Figures 2A, 2B, 2C, 2D and 2E).

Title: Grease expelling wheel bearing assembly
Inventor: ADKINS DAVID PAUL
IPC: F16C33/66
Filed: 1996-12-12
Abstract: A wheel bearing assembly (1) comprises a grease expelling seal (3), and a grease distributor (5).

Title: Brazing receptacle for improved PCD cutter retention
Inventor: KEITH CARL W
IPC: E21B10/567
Filed: 1997-06-03
Abstract: Thin walled metal alloy receptacles 26 are filled with a filler material. If granular, the filler material is solidified in the receptacles. The receptacles 26 are inserted in a bit mould with their open ends abutting against preformed cutter locations in the bit mould. The mould is filled with a steel or tungsten carbide powder and a binder and exposed to temperatures sufficient to cause the binder to infiltrate the steel or tungsten carbide as well as infiltrate the receptacle outer surfaces, metallurgically bonding the receptacles to the binder. The mould is then removed, revealing a bit body with the bonded filled receptacles. The filler material is removed from the receptacles. PCD cutters 12 are then inserted in the receptacles 26 and are brazed (34) using conventional brazing techniques.

Title: Wet gas meter with inclined level indicating tube
Inventor: RITTER JOACHIM
IPC: G01F23/02
Filed: 1997-08-14
Abstract: A wet gas meter has a casing 2 for receiving a blocking liquid 7, a gas inlet 4 and a gas outlet 10. A measuring drum 3 is located in the casing 2 and mounted for rotation about a horizontal axis 4. A level indicator tube 11 is in fluid communication with the interior of the casing 2, hence the level of the blocking liquid 7 in the tube 11 provides an indication of the level of the blocking liquid 7 in the casing 2. The level indicator tube 11 is inclined from the vertical at an angle of 1‹ to 89‹ so that a small change in the level of blocking liquid 7 in the casing 2 results in a larger change in the position of the surface of the blocking liquid 7 along the tube 11. The level of the blocking liquid 7 determines the volume of gas in measuring chambers 5 and therefore the volume of gas per revolution of the measuring drum 3.

Title: Optical image scanning system with improved image resolution
Inventor: KUO SHI-ZHENG
IPC: H04N1/193
Filed: 1997-08-21
Abstract: A method for improving the quality of an output image in an optical image scanning system. A step motor and a CCD sensor array are used to scan and acquire images. The timing of running the step motor and exposing the CCD sensor are carefully controlled so that the sensor is exposed to the reflected light of a scanned object when the motor is not moved. While the motor steps, the CCD sensor is turned off. The blurring effect of scanning is reduced and the modulation transfer function is improved.

Abstract: A 4-level direct conversion receiver demodulator 1 comprises an edge detector 2, a finite impulse response filter 3, an N-bit path 4, a data slicer 5 and automatic frequency control device 6. The edge detector 2 receives Limited I (LIMI) and Limited Q (LIMQ) signals on respective ones of first and second input leads 7 and 8 from a direct conversion receiver arrangement R. The edge detector 2 contains logic to provide an EDGE signal, comprising a short pulse when any edge is detected in either of the LIMI and LIMQ signals, on a line 9 and an I Lead Q (ILQ) signal, indicative of which of the LIMI and LIMQ signals has the leading phase, on a line 10 to the filter 3. The edge detector 2 thus determines both the frequency and the relative phase of the signals provided by the limited output direct conversion receiver R without the use of analogue to digital conversion circuitry. The N-bit path output 4 from the filter 3 is provided to both the data slicer 5 and to the AFC device 6. A demodulated output signal is provided in the form of an MSB and an LSB on respective ones of demodulator outputs 11 and 12. The modulator may be used in a direct conversion paging receiver.

Title: Eye position detector
Inventor: KIM SEONG-BEOM
IPC: G06T7/00
Filed: 1998-04-08
Abstract: In a system to detect eye position in a facial image comprising a plurality of pixels each represented by a grey level value, a window generator generates windows of the facial image and a histogram extractor creates a histogram for each window of number of pixels vs grey level value. When the number of peaks in the histogram equals 3, the sum of the areas of the peaks having the maximum and minimum grey level is calculated and co-ordinate information corresponding thereto is stored. The eye position is determined from the co-ordinate information corresponding to the window having the largest calculated area.

Title: Hand-held adhesive tape dispenser
Inventor: ADEFOPE BABATUNDE AYINLA
IPC: B65H35/00
Filed: 1998-06-04
Abstract: A hand held sticky-tape dispensing device enables a user single handedly, and in one single and continuous action, to very accurately place and dispense sticky-tape. Press-rollers (12 and 13), facilitate easy dispensing and ensure good adhesion, and once the required length of sticky-tape has been dispensed, the user can simply cut the tape using a push-button (6) operated integral cutting blade (11). The sticky-tape to be dispensed is housed in a fully enclosed custom designed cassette housing, wherein it can be stored indefinitely and kept in readiness for when it is next required. A tape viewing aperture built into the tape housing, allows the user to see how much tape is left on the reel before, during and after dispensing. Depression of button (6) also causes a rod (9) to deflect a guide (19) to capture the tape between the guide (19) and a pin (21) during cutting by the blade (11). The tape passes from spool (32) around an idle roller (16) and then around the guide (19) and roller (13).

When the engine is operating in a lean burn mode, rich correction are made to the engine air/fuel ratio in an amount dependent upon the combustion quality indications.
Patent GB-2342508-A (GB)
Title: Gripping electrical cables
Inventor: WEATHERLEY RICHARD
IPC: H01R13/58
Filed: 1998-07-08
Abstract: One method for gripping electrical cables comprises inserting a member 1 into the end of the cable sheath. The sheath can then be clamped between the arms 4 of the member and an external clamp, without putting pressure on the conductors, which run through longitudinal channels of the member. Another method uses a connector having a clamping member 14, 15. This is made as part of the connector (fig 7) but is broken off under pressure and latches into a new position. As the clamp is V-shaped it does not distort the cable as much as a flat clamp would. The methods can be used separately or together, and may be used in telecommunications connectors.

Title: Motor controller current sensor level shifter using pulse width modulation
Inventor: TAKAHASHI TOSHIO
IPC: H03M1/60
Filed: 1999-03-12
Abstract: A circuit for recovering a signal of interest which is offset by a common mode displacement, such as is the case when the signal is the voltage across a current sense resistor located on the high side bus or between the switches of a motor controller circuit. The circuit of the present invention converts the voltage across the resistor into a pulse code modulated data, then downshifts the voltage, and then recovers the signal of interest at the lower voltage by demodulating the signal. The recovered signal is then processed, either with a synchronized sample and hold circuit to provide an analog output, or with a counter and latch to provide a digital output.
